Smooth skin, smart choices: What to know before laser hair removal

Laser hair removal uses concentrated light energy to target the melanin in hair follicles. The energy heats and damages the follicle, slowing its ability to grow hair in the future. Over multiple sessions, the hair becomes finer, lighter, and significantly reduced. It is not an instant one-session miracle; it is a scientifically timed process.
One of the most important things to remember is that laser hair removal follows the body’s natural hair growth cycle. Only the hair in its active growth phase (anagen) responds effectively to the laser. Since not all hairs are in the same stage at the same time, you will need at least 6-10 sessions, spaced 4-6 weeks apart. Some stubborn areas like the chin, upper lip or hormonal zones may require more maintenance sessions.
Lasers work best when there is a clear contrast between the hair and the skin-such as light skin with dark hair. That said, newer technologies like Diode lasers, Nd:YAG lasers, and Triple Wavelength systems are safe for Indian skin tones too. However, white, grey, red or very light blonde hair responds poorly because these hairs have little pigment for the laser to target. Always choose a clinic experienced with your skin type.
Sun exposure increases the risk of pigmentation, burns or blotchy marks. It is best to avoid tanning, beach vacations, or prolonged sunlight at least 2 weeks before and after each session. Always step out with sunscreen (SPF 30 or higher), even on cloudy days.
Laser targets the root of the hair. Waxing, threading or epilating removes the hair root, making the laser ineffective. You must stop waxing 4-6 weeks before beginning laser sessions. Shaving, however, is allowed because it leaves the root intact. In fact, most clinics ask you to shave the area 12-24 hours before the appointment.
Most people describe the sensation as a warm pinprick or a rubber band snap. Modern lasers with cooling tips or chilling gels reduce discomfort significantly. If the pain feels sharp or burning, inform the technician immediately. Correct settings should never feel intolerable.
Redness, mild swelling around the hair follicles, or slight sensitivity for a few hours is normal. These usually settle on their own. Ice packs, aloe vera gel, and soothing creams help reduce the irritation. Avoid hot showers, saunas, intense exercise, or swimming for 24-48 hours after the session.
